When an economist turns into a winemaker

My friend Mitch Feierstein is a jolly, cheerful, life-enhancing fellow. He is emphatically not one of those economists whose purse-lipped response to any new phenomenon is ‘no good will come of this’ and who have predicted six of the past two recessions. But he is a profound pessimist. In a book he published last year, Planet Ponzi, he devotes page after relentless page to the troubles of the world economy.
